I was thinking about laying the flooring down first before adding cabinets but now that you mention it the wood floor would need room to expand and contract so fastening anything thru the wood flooring into the subfloor may not be a good idea?
I was just thinking it may be easier to lay the wood floor first instead of having to cut around everything.
Don't do it....
Though it is easier now
, what are you going to do if you get water damage or some other problem.
The so called pro's at the factory do it that way because its easier and cheaper, they are not concerned with anything after the initial sale.
In every step, think and plan with how I will replace, maintain or access this when I am done. It will be time well spent.Cliff
